Description of the problem

The editor is not direct tab key activable. The user needs to explicitly press enter key to activate it. Once inside the code editor , there is not way to come out unless I press esc.

This behavior is a little confusing for normal users. Is it possible to reduce complexity?

A few things noticed:

• it has a role as tab but doesn't follow the pattern of a tab, can read more here. Any reason behind this?
• on focus is not highlighted in file tabs
